General relativity is a physical theory about space and time and it has a beautiful mathematical description. According to general relativity, the spacetime is a 4-dimensional object that has to obey an equation, called the Einstein equation, which explains how the matter curves the spacetime. Wh...
What is gravitational waves (引力波)?Scientists have for the first time observed ripples in the fabric of space time (时空涟漪) called gravitational waves,arriving at the earth from a severely destructive event in the distant universe.It confirms a major prediction of Albert Einstein's 1915...
The source of gravity is mass and energy, according to Einstein's theory of general relativity, which describes gravity not as a force in the traditional sense but as a curvature of spacetime caused by mass and energy. Magnetism, however, originates from the spin and orbital motion of electro...
According to Einstein, gravity is a distortion of spacetime, the fabric of the universe itself. Mass warps space, like a bowling ball creates an indent on a bed sheet, and more massive objects like stars or black holes warp space with effects easily observed in a telescope - the be...
The dominating form of energy in the cosmos dark energy is driving the accelerating expansion of the universe, but its nature remains a mystery.
It is just emptiness, after all—a backdrop to everything else. Time, likewise, simply ticks on incessantly. But if physicists have learned anything from the long slog to unify their theories, it is that space and time form a system of such staggering complexity that it may defy our most...

Would it affect the very fabric of the universe? And is it even possible? Recommended Video for you: Play What Exactly is Spacetime? Explained in Ridiculously Simple Words Understanding Space And Time Einstein’s theory of general relativity implied that space-time is composed of four inseparable...
In 2017,astronomers observed for the first time gravitational waves, ripples in the very fabric of spacetime, and light that was sent radiating outwards from a collision between neutron stars. The signals that came from clashing binary neutron stars located 130 light-years away, verify the utility...
